Crest 3D White Strength Whitening Mouthwash — Clean Mint, Family 2-Pack, Alcohol-Free, Higher-Concentration Hydrogen Peroxide for Intensive Whitening (2 × 32 fl oz)

Strength Whitening sits at the top of Crest's whitening mouthwash hierarchy. Compared to Glamorous White at ~1.5% Hydrogen Peroxide, the Strength variant uses approximately 2% — meaningfully more aggressive whitening action through the rinse. Designed for users who've used Glamorous White and want stronger results, or who are using this as part of an intensive whitening cycle alongside Whitestrips and 3D White Platinum toothpaste.

2 bottles × 32 fl oz (64 fl oz / 1.89 L total). At normal use (10-20mL, 2× daily), each bottle lasts ~5 weeks; the pack provides ~10 weeks. Clean Mint is a brighter, more energetic flavor than Glamorous's Arctic Mint. Best used as part of a finite whitening cycle rather than a permanent daily mouthwash — peroxide-based mouthwashes are best in cycles.

1. Brush teeth with a whitening toothpaste first.
2. Pour 10-20 mL of mouthwash into the cap.
3. Swish vigorously for 60 seconds around all teeth surfaces.
4. Spit out. Do NOT swallow.
5. Do not eat or drink for 30 minutes after for maximum peroxide contact.
6. Use 2× daily for 4-8 weeks (an intensive whitening cycle), then switch to a gentler maintenance mouthwash.
7. Adults only — do NOT use in children under 12.

Korean shoppers serious about whitening often build complete cycles: 3D White Strength Whitening mouthwash + 3D White Platinum toothpaste + 3D Whitestrips Professional. This product is the mouthwash component of that aggressive routine. The 2-pack allows for a full 10-week cycle with adequate supply.

The Clean Mint flavor is distinct from the Arctic Mint of Glamorous — sharper and brighter, often described by users as feeling "medicinal" in a positive sense ("my mouth feels like it's been deep-cleaned"). Korean shoppers who like the Crest 3D White product lineup tend to gravitate to this top-tier variant.
